Comprehension Questions

Question	Answer
What is an ADT?	An abstract data type that is defined by the methods and not which type of data structure it uses ie an array or a linked list
Describe a Stack	A method of storing data that uses last in first out. Like taking the most recent book you bought off of a stack of other books you bought that you swear you'll get around to reading.
What are the 5 methods in Stack and what does each do?	push: to add an object to the top of the stack, pop: to removed an item from the top of the stack, is empty: to check if the stack is empty, peek: to look at but not remove the top element of the stack, and size: to tell you the size of the stack
Describe a Queue	A queue is an ADT that operates on a first in first out basis like a long line for ice cream on a day that reminds you global warming is very real.
What are the 5 methods in Queue and what does each do?	enqueue(item): adds an item to the end of the queue, dequeue: removes an item from the beginning of the queue, is_empty: says true if its empty or false if it's not, front: returns the first element but doesn't change it, and size: returns the size of the queue.
What is the difference between implementing something and using something?	I'm not completely certain on this reading, but I believe you mean that implementing is how doing something how it was designed to be used whereas using it is just doing it, however. I can use a screwdriver to hammer in a nail, but that's not how it was designed to be implemented?

Just be aware you can do things like:

Suggested change

	elsif @front + 1 == MAX_SIZE
	@front = 0
	else
	@front += 1
	end
	else
	@front = (front + 1) % MAX_SIZE
	end
